Answer 1

8.10
The Colorado River Drainage Basi covers parts of seven western states. A
series of dams has been constructed on the Colorado River and its
tributaries to store runoff water and to generate low-cost hydroelectric
power (see Figure P8.10). The ability to regulate the flow of water has
made the growth of agriculture and popluation in these arid desert states
possible. Even during the periods of extended drought, a steady, reliable
source of water and electricity has been avaialble to the basin states.
Lake Powell is one of these reservoirs. The file lake_powell.dat containts
data on the water leve in the reservoir for the 8 years from 2000 to 2007.
These data are shown in Table 8.11. Use the data in the file to answer the
following questions:

(a) Determine the average elevation of the water level for each year and for
the 8-year period over which data were collected.
(b) Determine how many months each year exceed the overall average for the
8-year period.
(c) Create a report that list the month (number) and the year for each of
the months that exceed the overall average. For example, June is month 6.
(d) Determine the average elevation of the water for each month for the
8-year period.
